Currently, when the cab is mounted, the cab is connected to the front suspension assembly, and then the front suspension assembly is mounted on the frame. Before the front suspension assembly is arranged on the frame, the lower support of the shock absorber is fixedly connected with the frame; when the front suspension assembly is installed, the height difference is reserved between the front suspension assembly and the lower support of the shock absorber, so that the shock absorber is connected between the front suspension assembly and the frame. When the shock absorber is installed, the air spring of the shock absorber is in an uninflated state, and at the moment, the bottom end of the shock absorber is fixed with the lower support of the shock absorber, so that the bottom end of the shock absorber is fixedly connected with the frame; after an air spring of the shock absorber is inflated, the shock absorber is connected with the front suspension assembly through an upper lifting lug at the top end of the shock absorber. Therefore, when the front suspension assembly is installed on the frame, the relative height between the front suspension assembly and the lower support of the shock absorber needs to be accurately determined, and a reserved space is set for the height of the shock absorber after being inflated.
In the prior art, a height positioning device is disposed between a stabilizer bar of a front suspension assembly and a bumper of a vehicle frame, and the height positioning device is configured such that both ends thereof are arc-shaped concave surfaces and contact with a cylindrical stabilizer bar and a cylindrical bumper, respectively. However, the height of the front suspension assembly cannot be accurately determined by the conventional height positioning device, so that after the shock absorber is installed, the distance between the top end of the shock absorber and the bottom end of the shock absorber is not equal to the normal height of the shock absorber after inflation, and an upper lifting lug of the shock absorber has pretightening force, is deformed and accelerates workpiece aging.
Therefore, there is a need for a positioning device that can accurately determine the height of a front suspension assembly.
FIG. 1 is a schematic view of an embodiment of the present application illustrating the assembly of a positioning device; fig. 2 is a schematic structural diagram of a positioning device in an embodiment of the present application.

The top end of the shock absorber is connected to the stabilizer bar assembly of the front suspension assembly 20, and the bottom end of the shock absorber is connected to the bottom of the shock absorber lower bracket 10. When the shock absorber is at a normal height, the shock absorber lower bracket 10 is not in contact with the front suspension assembly 20, and the shock absorber lower bracket 10 has the function that when the shock absorber is compressed to a certain height, the top end of the shock absorber lower bracket 10 abuts against the front suspension assembly 20 to prevent the shock absorber from being compressed continuously. Specifically, the lower bracket 10 of the shock absorber includes a stopper 12 provided at a top end thereof, and contacts the front suspension assembly 20 through the stopper 12.
